Start questioning a woman's ability in the country (6)
I believe the answer is:
canada
'ability in the country' is the definition.
'canada' can be an answer for 'country' (Canada is an example). I am not sure about the 'ability in the' bit.
'start questioning a woman's' is the wordplay.
'start questioning' becomes 'can' (I can't explain this - if you can you should give a lot more credence to this answer).
'a woman' becomes 'Ada' (woman's name).
'can'+'ada'='CANADA'
Can you help me to learn more?
(Other definitions for canada that I've seen before include "Queen Elizabeth is it's head of state" , "Country with six time zones" , "North American goose" , "North American nation" , "N American nation" .)
